[0002] The male connector is a component used on a circuit board for electrical connection. The male connector can be inserted and mated with the female connector.

[0003] One related technology includes an electrical connector male socket comprising an injection-molded insulating component, on which power terminals and signal terminals are provided. The power terminals are connected to solder feet for connection to a circuit board.

[0004] When the male connector of an electrical connector is frequently plugged and unplugged from the female connector of an electrical connector, the solder feet of the power supply terminals are prone to plastic deformation or breakage. Utility Model Content

[0005] To improve the bending resistance of power terminals, this application provides a male electrical connector socket.

[0006] This application provides a male electrical connector socket, which adopts the following technical solution:

[0007] A male electrical connector socket, comprising

[0008] Insulating body,

[0009] The power terminals are mounted on the insulating body.

[0010] The insulating body includes a base portion and two first sidewall portions disposed above the base portion. The two first sidewall portions are symmetrical to each other and are located at the ends of the base portion along the length direction of the insulating body.

[0011] The power terminal includes a top portion, a second side portion disposed on one side of the top portion along the width direction of the insulating body, and a solder foot disposed on the side of the second side portion away from the center of the first side wall portion. The first side wall portion has a mounting hole for accommodating the second side portion, and the solder foot is perpendicular to the second side portion.

[0012] By adopting the above technical solution, after the male connector is connected to the circuit board through the solder feet, the unbent second sidewall can improve the strength when the male and female connectors are inserted and removed, making the power terminals less prone to deformation, bending and breakage, and even if the power terminals are not easily damaged; the solder feet are perpendicular to the second sidewall, so that when the male connector is pulled out of the female connector, there will be no deformation or breakage, effectively protecting the insulation body.

[0013] Optionally, the power terminal further includes a first side portion disposed on the top surface facing the base portion and a locking portion disposed on the side of the first side portion away from the top surface. The locking portion is arched toward the center of the base portion. A first mounting groove for accommodating the first side portion is provided on the first side wall portion, and a locking hole for accommodating the locking portion is provided on the inner wall of the base portion facing the first mounting groove.

[0014] By adopting the above technical solution, when the male connector is pulled out of the female connector, the power terminal will be subjected to the frictional force of the pulling action, and the locking part is in the locking hole, which improves the connection between the male connector and the power terminal and prevents the power terminal from detaching from the insulating body.

[0015] Optionally, the power terminal further includes an extension disposed on the top surface facing the base portion, and a second mounting groove for inserting the extension is provided on the first sidewall portion.

[0016] By adopting the above technical solution, the extension can effectively protect the side of the electrical connector male socket during the insertion and removal process of the electrical connector male socket and the electrical connector female socket.

[0017] Optionally, the top surface is provided with a third side surface at both ends along the width direction of the insulating body.

[0018] By adopting the above technical solution, when the male connector and the female connector are plugged in, the third side can increase the contact area between the power terminal and the mating terminal on the female connector, thereby improving the stability of the electrical connector when conducting electricity.

[0019] Optionally, it also includes signal terminals, wherein a plurality of signal terminals are provided and all are mounted on the insulating body. The insulating body also includes two second sidewall portions provided on the base portion. The two second sidewall portions are symmetrical to each other and extend along the length direction of the insulating body. Each end of the second sidewall portion along the length direction of the insulating body is connected to a first sidewall portion. At least two grooves are provided on the side of the two second sidewall portions that are far apart from each other. Signal terminals located between two adjacent grooves are provided on the second sidewall portions.

[0020] By adopting the above technical solution, when the insulating body is injection molded, the groove on the second side wall has the function of isolating the plastic, preventing the plastic from covering the signal terminal and reducing the probability of circuit breakage.

[0021] Optionally, a transition groove is provided on the upper end face of the second sidewall. A fixing groove and a fixing hole are provided on the inner wall of the transition groove near the base. The fixing hole is located on the side of the fixing groove near the central axis of the base. A storage groove is provided on the inner wall of the base along the width direction. A through hole communicating with the fixing hole is provided on the side of the storage groove near the second sidewall. The signal terminal includes a transition part disposed in the transition groove, a conductive part disposed in the storage groove, an inner fixing part and an outer fixing part disposed on the side of the transition part facing the conductive part. The outer fixing part is disposed in the fixing groove, and the inner fixing part is disposed in the fixing hole. The end of the inner fixing part away from the transition part is connected to the conductive part.

[0022] Optionally, a protrusion is provided on the inner wall of the fixing groove near the fixing hole, and a notch is provided on the outer fixing part for the protrusion to be inserted.

[0023] By adopting the above technical solution, when the male connector is pulled out of the female connector, the outer fixing part is subjected to a force away from the base part, and the protrusion is in the notch groove, which plays a blocking role in the movement of the outer fixing part, making it difficult for the outer fixing part to fall out of the fixing groove.

[0024] Optionally, the external fixation part has a protrusion on the side away from the internal fixation part.

[0025] By adopting the above technical solution, the protrusion can engage with the elastic locking arm on the inner terminal of the electrical connector female, thereby improving the firmness of the connection between the electrical connector male and the electrical connector female.

[0026] Optionally, the outer fixing part is provided with a chamfer, which is located at the junction of the side of the outer fixing part facing the transition part and the side of the outer fixing part away from the inner fixing part. The fixing groove is provided with a stop block that can connect with the chamfered surface near the inner wall of the base part.

[0027] By adopting the above technical solution, when the external fixing part moves away from the internal fixing part, it will be blocked by the stop block, which plays a limiting role and makes it difficult for the external fixing part to detach from the fixing groove.

[0028] Optionally, a slot is provided on the side of the internal fixing part away from the external fixing part.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. After the male connector is connected to the circuit board via solder feet, the unbent second sidewall can enhance the strength of the male and female connectors during insertion and removal, making the power terminals less prone to deformation, bending and breakage, and even if the power terminals are not easily damaged; the solder feet are perpendicular to the second sidewall, so that when the male connector is pulled out of the female connector, there will be no deformation or breakage, effectively protecting the insulation body.

[0031] 2. The fit between the bump and the notch / groove prevents the signal terminal from easily separating from the insulating body during insertion and removal of the male and female connectors. Attached Figure Description
